Breaker defect... There is not breaker protection, it is only one functionin the new protective relays, or two time relays in the old prorective technology. The breaker protection does: If the breaker gets open command from a protection, the time relay starts, the breaker opened,the relay stops, if the breaker don't open, the time relay send open command to the all connected breakers, and there is not so big arcs. There need new disconnector..2nd: operator mistake: There was current in one phase

Even if electricity wasn't such a boon to civilization, this would justify us harnessing it. Because fuck yeah.

This is an arc, but it's not really what "arc flash" means. An arc flash is more like a bomb going off.

I was at The National Grid HQ midlands two days ago and they showed us this exact clip! It's pretty damn cool:) it's called a circuit breaker in the main power lines that are carrying around 400,000 volts, and a fault caused the energy to continue flowing and ark! Then once the distance between the two current carrying substances got too great, the ark cut out, Awesomee Lol:)

They are trying to switch a line reactor out of the circuit. This particular piece of switchgear was malfunctioning. The insulator looking things to the left of the air break switch blades are sulfur hexafluoride switches. One of the ones in the affected phase was defective and caused the air break blades to open "hot," pulling that magnificent arc. They extinguish it by opening an upstream circuit breaker.
